Bonemen are black skeletons found within the Soul Cairn. You can summon them to fight for you after learning Conjure Boneman from a spell tome in the Soul Cairn. Like other creatures found in the Soul Cairn, bonemen leave behind a pile of black "soul ashes" when defeated. These yield a random-sized soul gem and a Soul Cairn alchemical ingredient, and have a 10 percent chance of containing an inexpensive piece of jewelry. Durnehviir, whether fighting for or against you, will summon bonemen in combat.
